In response to climate targets set by the Swedish Climate Act aimed at achieving net-zero greenhouse emissions by 2045, this study investigates the potential of renewable biochar as a replacement for fossil carbon in electric arc furnace (EAF) steelmaking. The objective is to establish an experimental basis for biochar's performance as a carburizing agent, given that a significant portion of greenhouse gas emissions in EAF steelmaking stems from fossil carbon used during the melting of steel scrap. Using lab-scale tests, this research evaluates four carbonaceous materials: synthetic graphite, anthracite coal, and two types of biochar produced from woody biomass (BC1 and BC2). The study assesses the first order dissolution rate constants which ranged between 0.7 to 1.9 × 10−4 m/s, aligning with previously reported findings. The results indicate that biochar can effectively replace fossil carbon, providing a straightforward means to reduce the climate impact of steelmaking while supporting the transition to more sustainable practices in the industry.
